Getting Started

Dynamic IP addresses:

By default, UC-7420/7410 is configured for “static” IP addresses. To configure one or both LAN ports to request an IP address dynamically, replace static with dhcp and then delete the address, network, netmask, and broadcast lines.

Default Setting for LAN1	Dynamic Setting using DHCP
iface ixp0 inet static	iface ixp0 inet dhcp
address 192.168.3.127
network: 192.168.3.0
netmask 255.255.255.0
broadcast 192.168.3.255

3.After the boot settings of the LAN interface have been modified, issue the following command to activate the LAN settings immediately:

#/etc/init.d/networking restart
